• Thus
  • Relative lengths of SCs are almost equal to the relative lengths of mitotic chromosomes of spermatogonia (with the exception of the X chromosome), thus extending to an invertebrate the relationship between SCs and mitotic chromosomes that has been demonstrated in mammals. (biologists.org)
  • although
  • The idea of morphological reduction of W is also enhanced by our perspective of the gradual shortening of human Y chromosome [ 5 ], although there are examples of Y becoming larger than X in non-human species [ 2 ]. (royalsocietypublishing.org)
  • Although these sex chromosomes do not recombine, they segregate reductionally in anaphase I. We have investigated the nature of sex chromosome association in spermatocytes of the marsupial Thylamys elegans, in order to discern the mechanisms involved in ensuring their proper segregation.
